2,000,000 times
Explanation:
One gram of U-235 produces approximately 2,000,000 times more energy than one gram of coal.
The energy in 1g of U-235 is a nuclear energy whereas energy obtained from coal is chemical energy by combustion. During combustion chemical bonds are broken between the carbon atoms.
- Uranium decays the radioactive fission.
- When it is bombarded with particles, an artificial disintegration is induced.
- Most nuclear reactions are chain reactions in which one step leads to another until stability is produced.
- Each step produces energy for the next process.

Using the given formula, the density of the material is 2.015 g/mL
<h3>Calculating Density </h3>
From the question, we are to determine the density of the material
From the given formula
Density = Mass / Volume
And from the given information,
Mass = 65.5 g
and volume = 32.5 mL
Putting the parameters into the equation,
Density = 65.5/32.5
Density = 2.015 g/mL
Hence, the density of the material is 2.015 g/mL.

For b) Na₂[Os(CN)₆]
Os configuration = d⁶s²
In this complex Os oxidation number is +4
Os⁴⁺ configuration = d⁴
number of
electrons = 4
True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.
